2014-04-01: Stabilizers

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2014-04-01 Slingsby Aviation Ltd.: Amendment 39-17759; Docket No. FAA-2013-0997; Directorate Identifier 2013-CE-044-AD. (a) Effective Date This airworthiness directive (AD) becomes effective April 1, 2014. (b) Affected ADs None. (c) Applicability This AD applies to Slingsby Aviation Ltd. Model T67M260 airplanes, all serial numbers, certificated in any category. [[Page 10344]] (d) Subject Air Transport Association of America (ATA) Code 55: Stabilizers. (e) Reason This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracked horizontal stabilizer attachment brackets. We are issuing this AD to prevent separation of the horizontal stabilizer, which could result in loss of control. (f) Actions and Compliance Unless already done, do the actions specified in paragraphs (f)(1) through (f)(4) of this AD: (1) Within the next 150 hours time-in-service (TIS) after April 1, 2014 (the effective date of this AD) or at the next annual inspection after April 1, 2014 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 150 hours TIS, inspect the aluminum horizontal stabilizer attachment brackets for cracks. Do the inspections following the ACTION instructions in Slingsby Advanced Composites Ltd. Service Bulletin S.B. No: 179, Issue 4, dated March 15, 2007. (2)If any cracks are found during any inspection required in paragraph (f)(1) of this AD, before further flight, replace the cracked bracket with a serviceable part. Do the replacement following the ACTION instructions in Slingsby Advanced Composites Ltd. Service Bulletin S.B. No: 179, Issue 4, dated March 15, 2007. If a serviceable aluminum horizontal stabilizer attachment bracket is used as a replacement part, repetitively inspect as specified in paragraph (f)(1) of this AD. (3) To terminate the repetitive inspections required in paragraph (f)(1) of this AD, all four aluminum horizontal stabilizer attachment brackets must be replaced with titanium horizontal stabilizer attachment brackets. (4) After installing titanium horizontal stabilizer attachment brackets, installing aluminum horizontal stabilizer attachment brackets is prohibited. (g) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number.
